SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 242,313, dated May 31,1881.

' Application filed April 7, 12st. (Model) To all whom it may concern:

Be it known that I, HUBERT HEBERT, of Lake Linden, in the county ofHoughton and State of Michigan, have invented a new and ImprovedSpring-Bed, of which the following is a full, clear, and exactdescription.

The invention consistsin a spring-bed formed of a series of slatsresting on crossed inclined spring-slats, the outer lower ends of whichare fastened to the longitudinal side bars of a base-frame, whereas themiddle of these springslats is supported by two adjustable longitudinalrails passing through the middle of the base-frame, by means of whichmiddle rails the elasticity of the spring-slats can be adjusted.

In the accompanying drawings, Figure 1 is a plan vicwof my improvedspring-bed, showing some of the upper slats and some of the spring-slatsremoved. Fig. 2 is a cro'sssectional elevation of the same on the line00 00, Fig. 1. Fig. 3 is a longitudinal sectional elevation of the sameon the line y y, Fig. 2.

Similar letters of reference indicate corresponding parts.

The slats A are provided with short longitudinal slots B at the ends,and through these slots screws or rivets 0 pass into the ends of crossedspring-slats D, the lower ends of which are fastened to the longitudinalrails E of a base-frame, F, these spring-slats D passing from one end ofthe slats A to the opposite longitudinal rail E of the base-frame.spring-slats D rest, near the center,on the longitudinal rails G, havingtheir upper surfaces beveled toward the ends of the base-frame andpassing through the middle of this base-frame. These centrallongitudinal rails G are secured 011 the transverse end rails 1-1 of thebaseframe by strips J and screws L, and are provided on their uppersurfaces with blocks K for separating the spring-slats D from each otherand keeping them in place. The middle longitudinal rails, G, areadjustable, and it they are separated the elasticity of the springslatsis decreased, whereas it they are brought togethertheelasticityoftheseslatsisincreased, their inclination. varyingaccordingly.

The slats A and the spring-slats D are preferably made of wood, but mayhe made of metal.

Having thus described my invention, Iclaini as new and desire to secureby Letters Patent In a spring-bed, the combination, with the slats A, ofthe spring-slats D, the base-frame F, the adjustable rails G G, and thestrips J, substantially as herein shown and described, and for thepurpose set forth.

HUBERT HEBERT.
